Http://www.fixya.com/support/t469463-akai_lct3201_ad_power_supply

I cracked open this TV how ever I do not see any weeping, leaking or burned capacitors. I have not popped out the power supply nor removed the heat sinks (where the problem may be) I just want to make sure this is the issue before i start to test cut and repair. Is this always the issue with this tv? Wheres the weak link on the power supply and where else are they on the TV?
thanks a head of time for your time.

On the power supply board if it has capacitors that are raised in the center and not flat then that is you problem.this can be an issue with any model flat screen tv. 80% of the time this is what's wrong.same for computer monitors also.

My AKAI tv model LCT2715 is not turning on and when I take it off stanby and try turning it on a orange light starts blinking so how do I fix it so I can use my tv again


It may be in the safety shutdown mode due to shorted circuits or failed power supply due to bad caps, I would inpsect the power supply first for caps with doemd tops.
Here are the service manuals: http://elektrotanya.com/?q=showresult&megnev=akai&megnev2=LCT2715&kategoria=tv&kat2=all

Replacement boards, try www.shopjimmy.com'

You need to do more torubleshooting, bad caps can look normal but they can have high ESR which are bad for switching power supply circuits.
Need to check the DC voltages, also try disconnecting the power cables to the backlights inverter board to see if it will come on normally isnce the light blinking can indicating it is sensing shorted circuits so it goes into shutdown/restart mode.

Akai TV power supply problem.


Completely understandable concern. I have fixed 9 AKAI LCT2715 power supplies for other people who have contacted me through fixya.com and 2 through my instructable on instructables.com.

I did notice that you posted this under AKAI LCT3201 TD 32in. LCD Television TV/DVD Combo troubleshooting... I do not remember posting to anything other than the problems concerning AKAI LCT 2715 27in TV's. But in any case this could be the same issue for you as I have noticed a common failure point on AKAI TV's is due to the poor power supply components they use.

As far as trust is concerned I can not really say anything more other than I do keep in contact via email about the parts that are shipped to me to let the customer know when it arrives as well as discussing payment options up front so you know what to expect. I also offer paypal as a payment option and I send an invoice via paypal when the power supply is ready to ship.

Thank you for your question and I hope this helps you understand how this general process works for more cases.

I would bet on the power supply....these (and other Akai LCD) are notorious for filter capacitors. Look for electrolytic capacitors with a dome-like bulge on the top of them. They are usually located at the top of the power supply board where the power output lines run out.

 

Hpe this helps you out....
